Rumors aplenty have been swirling about AMD's new HD 5900 series but NVIDIA hasn't been sitting on their laurels either. In order to preempt the release of AMD's upcoming flagship products, a new GeForce branded card is being introduced today. Dubbed the GTX 580, it uses a newly tweaked GF110 core along with higher clock speeds than the GTX 480 and the result is a class-leading card that dominates the single GPU landscape.

I would so buy one of these if they weren't selling for $570!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Way too steep a price for me. I've also been waiting for the GIGABYTE GTX 480 Super Overclock mainly to see where it would be priced. I hope AMD isn't really going through delays for their high-end cards, otherwise this holiday season will suck for people in the high-end market. :(

Could you clarify how the power efficiency vs temp test was done? It sounds like you ran the same F@H WU over and over at different fan speeds, but the 70% fan comment makes it sound like something else.

Also curious to know if you looked at the fan OEM when you took the heatsink off.

Also curious if you know why Nvidia didn't put a hole on the back of the PCB this time around.

Price is where I thought it would be and performance is very good. wondering if I made the right choice going with 2 460's or waiting. lol oh well. I'll wait for price drops or more stock for these lol
